You didn't import "defaultConstructors", so your code is erroring out
during the initialize.

Also, there is no reason to register the base class for your user source
unless you plan to make a ZClass subclass of it, which isn't supported in
any released version of ZPatterns.  (0.4.3 will support ZClass subclasses
of PlugIns and PlugInContainers, but you'll have to jump through slightly
different hoops to make them work.)
